چکیده:

Titania (in the amorphous phase), impregnated with polyoxometalates, have been prepared and these composite catalysts have presented much higher catalytic activity than that of the starting polyoxometalates [1,2]. In this paper, we designed and prepared anatase TiO2 nanoparticles coupled by homogeneously dispersed polyoxometalate at 200 oC via combination of the sol-gel technique with the programmed temperature hydrothermal method. The catalyst easily separated and reused at the end of reaction without a significant loss of its catalytic activity, which suggests that the catalyst is stable under different conditions
